실험 절차

A mixture of 6.0 g of 4-[5-(3,5-dichlorophenyl)-5-trifluoromethyl-4,5-dihydroisoxazole-3-yl]-2-methyl benzoic acid amide synthesized in Step 1 of Synthetic Example 19 and 50 mL of N,N-dimethylformamide dimethylacetal were stirred at 120° C. for 1.5 hour. After the completion of the reaction, the solvent was distilled off under reduced pressure. The residual solid was washed with ethyl acetate-hexane mixture (1:20) to obtain 6.2 g of the aimed product as pale yellow crystal.
